Irregular suture diameter measuring device and method

The invention provides an irregular suture diameter measuring device and method, and belongs to the field of medical suture detection. The measuring device is mainly composed of a dial indicator, a presser foot, a fixed reference table, a positioning block, a fixed base, a pedal plate, a lifting line and an acquisition device. According to the measuring method, automatic lifting of the presser foot is achieved mainly by stepping on a pedal, after the presser foot makes contact with a sewing thread, the thread diameter values of two vertical faces are accurately measured, and a collecting device collects the measured thread diameter values and then automatically calculates an equivalent thread diameter value. According to the principle that the model area of the natural non-circular section suture is equal to the circular area, the equivalent line diameter test measurement method suitable for the natural non-circular section suture is established by measuring the line diameter values of two vertical surfaces o
